Description
Technical field
The utility model relates to Blast Furnace Top Gas Recovery Turbine Unit (TRT), and relating in particular to can off-grid photovoltaic power generation apparatus.
Background technology
The generating of the main power generation mode that China is present or coal, this power generation mode pollutes large, consumption be non-renewable energy resources, the capital construction of required input is many, especially is difficult to popularization and application in the west area.
Solar power generation is divided into photo-thermal power generation and photovoltaic generation.Usually the solar power generation of saying refers to solar energy power generating, is called for short " photoelectricity ".Photovoltaic generation is to utilize the photovoltaic effect of interface and a kind of technology of luminous energy directly being changed into electric energy.The key element of this technology is solar cell.Carry out packaging protection after solar cell passes through and connects and to form large-area solar module, cooperate again parts such as going up power controller just to form photovoltaic power generation apparatus.And existing photovoltaic power generation apparatus can only provide direct current or alternating current mostly, and pattern is single.
The utility model content
The technical problems to be solved in the utility model is that existing photovoltaic power generation apparatus can only provide direct current or alternating current, supplies a pattern singlely can not satisfy diversified demand, provide for this reason a kind of can off-grid photovoltaic power generation apparatus.
The technical solution of the utility model is: can off-grid photovoltaic power generation apparatus, it comprises solar energy photovoltaic panel, MPPT controller, storage battery and from the net inverter, described solar energy photovoltaic panel is electrically connected with the input of described MPPT controller, the output of MPPT controller is connected with described storage battery, and storage battery is electrically connected with described input from the net inverter.
The output of the controller of MPPT described in the such scheme is connected with DC load.
The beneficial effects of the utility model are that the electric energy that solar module produces passes through the MPPT controller to charge in batteries; The storage battery of energy storage can directly be given the DC load power supply of LED class by the MPPT controller; Also can supply with through the inverter conversion simultaneously the electricity consumption of household appliances; Need not civil power, fully by solar powered.The present invention can better use in western remote districts, and cost is low, the life-span is long, the advantage of environmental protection.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises solar energy photovoltaic panel, MPPT controller, storage battery and from the net inverter, solar energy photovoltaic panel is electrically connected with the input of MPPT controller, and the output of MPPT controller is connected with storage battery, and storage battery is electrically connected with input from the net inverter.
The PV of at first solar energy photovoltaic panel, storage battery and MPPT controller being connected carries out correct positive and negative connection with the BAT input; PV namely is photovoltaic, and BAT namely is battery, then will link to each other with the accumulator positive negative terminal from the net inverter input terminal; Because what use is the MPPT controller, the generating efficiency of performance cell panel that like this can be larger; The cabinet of at last storage battery, controller, inverter all being packed into, connection line; End user only need open switch when using, and plugs wiring board and can power to the household electrical appliance load;
The full name of MPPT controller " MPPT maximum power point tracking " (Maximum Power Point Tracking) controller for solar is the upgraded product of traditional solar charging/discharging controller.The MPPT controller can the detecting real-time solar panels generating voltage, and follow the trail of ceiling voltage current value (VI), make system with maximum power output to charge in batteries.Being applied in the solar energy photovoltaic system, coordinating the work of solar panel, storage battery, load, is the brain of photovoltaic system.
Maximum work point is followed the tracks of (Maximum Power Point Tracking, abbreviation MPPT) system is a kind of by regulating the operating state of electrical module, the direct current that the electrical system that makes photovoltaic panel can export more electric energy can be sent solar panel is stored in the storage battery effectively, can effectively solve remote districts that conventional electrical network can not cover and life and the commercial power of tourist area, not produce environmental pollution.
Package unit of the present utility model can be contained in the cabinet, is provided with accordingly status display interface and input and output interfaces; This system also is equipped with terminal block simultaneously; Can be provided with wheel under the whole cabinet can move very easily, is specially adapted to the area that set up without electrical network in western part.
Solar energy photovoltaic panel flows to storage battery power supply to light energy conversion as electric energy and electric energy by the MPPT controller when using, and the storage battery of energy storage can directly be given LED class or other direct current class load supplying by the MPPT controller on the one hand; Also can pass through the electricity consumption of supplying with household appliances from the conversion of net inverter on the other hand, flexible and convenient to use.
